Question
- A. To make water taste better
- B. To ensure water is safe to drink
- C. To increase water availability
- D. To reduce water costs
Answer
The correct option is To ensure water is safe to drink. This answer is correct because it matches the approved learning objective to describe sterilisation as part of potable water treatment in the subtopic Potable water.
Explanation
The correct option is To ensure water is safe to drink. To ensure water is safe to drink is correct because it directly supports the approved learning objective to describe sterilisation as part of potable water treatment. This belongs to the subtopic Potable water within Using the Earth's resources and obtaining potable water, so the explanation must stay tied to that curriculum context. The other options are incorrect because they either do not answer this learning objective, use a vague statement, or move away from Potable water.
Common mistake
Confusing Sterilisation Methods
Students often confuse sterilisation methods for potable water, thinking that all methods are the same.
Do not treat this as a general statement about potable water. Instead, answer by clearly linking the correction to describe sterilisation as part of potable water treatment in Potable water. This keeps the response inside Using the Earth's resources and obtaining potable water and prevents a vague or off-topic GCSE answer. The mistake to avoid is: students often confuse sterilisation methods for potable water, thinking that all methods are the same.
